Compression Shearing Action
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.


Three-flute right-hand compression router bit for CNC routing laminated or veneered wood and wood composites where both top and bottom finish are critical. The current live Royce Ayr specification lists a 1/2-inch cutting diameter, 7/8-inch cutting edge, 0.380-inch upcut section, 1/2-inch shank, and 3-inch overall length.
Three-flute HW/carbide compression geometry with right-hand rotation. Upward and downward shearing action is designed to control chipping on both faces of laminated or veneered wood and wood-composite panels.
Designed for compatible CNC routers using precision 1/2-inch collets or approved 1/2-inch toolholding systems for nested routing, profiling, and compatible dado operations.
The Royce Ayr R60-12102 is a three-flute compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. The current live Royce Ayr series table lists a 0.5000-inch cutting diameter, 0.875-inch cutting edge, 0.380-inch upcut length, 0.500-inch shank, three flutes, right-hand rotation, and a 3.000-inch overall length.
Compression geometry combines upward and downward shearing action so both panel faces are supported during routing. Royce Ayr specifies this action to help prevent chipping of laminates, while the short upcut section supports chip-free dado routing in compatible laminated and veneered panel applications.
The current live series identifies this exact base SKU with coating type None and places the family in Royce Ayr's Solid Carbide Tooling range. Correct collet condition, runout, tool projection, spindle speed, feed rate, pass depth, workholding, entry strategy, and extraction remain essential for repeatable production.
Technical Specifications
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.
The current live Royce Ayr series database lists R60-12102 with a 0.380-inch upcut section, paired with a 1/2-inch diameter and 7/8-inch cutting edge.
R60-12102 is the coating-None base configuration, distinct from the otherwise matching Ultimax-coated R60-12102UM variant.
Confirm that the CNC router toolholder accepts the exact 1/2-inch (12.70 mm) shank and provides suitable clearance for the 3-inch overall tool length. Verify right-hand spindle rotation, inspect the collet and nut, minimize unsupported projection, check runout, secure the workpiece, and establish spindle speed, feed rate, pass depth, entry strategy, and extraction for the actual laminated, veneered, or wood-composite panel. This page uses the current live Royce Ayr series specification of 0.380 inch for UPCUT.
Royce Ayr R60-12102 combines a 1/2-inch diameter, 7/8-inch cutting edge, 0.380-inch upcut section, 1/2-inch shank, three-flute compression geometry, right-hand rotation, coating None, and a 3-inch overall length.
Its opposing shearing action is designed to protect both panel faces from laminate chipping while supporting chip-free dado routing in laminated or veneered wood and wood-composite production.
